Many billions have been poured into the business in terms of AI processor improvement. If you have been to listing the variety of AI processors presently in improvement or manufacturing at the wide range of start-ups, then that quantity rapidly surpasses 50 and is seemingly without end rising. Each one in every of these corporations is aiming to construct a compelling product to fulfill the wants of their supposed prospects, all the way in which from small-scale inference workloads as much as multi-datacenter scale coaching. One of those corporations is Tenstorrent, led by CEO Ljubisa Bajic, who not too long ago employed famed chip designer Jim Keller because the CTO. Jim was additionally the preliminary angel investor when the corporate began. Today we’re interviewing these two concerning the firm, the Tenstorrent product, and the path of the calls for for machine studying accelerators.
This interview was considerably sudden – a few month in the past Jim Keller reached out to me to ask if we wished to interview him and Ljubisa concerning the firm. We had highlighted at the beginning of the 12 months when Jim was employed by Tenstorrent, and I’ve sat by means of numerous Tenstorrent displays by Ljubisa and his group, so no matter firm Jim lands at will get a whole lot of consideration. Apparently my title was advisable to achieve out for an interview, and right here we’re!
We really cut up the interview into two segments. This is the primary 90-minute interview transcription, on the subject of Tenstorrent with Ljubisa and Jim. There shall be a second 90-minute interview to comply with, on the subject of Jim Keller, subsequent week.

Ljubisa Bajic is a veteran of the semiconductor business, working extensively in VLSI design and debug coupled with in depth accelerator structure and software program expertise. Ljubisa spent a decade inside AMD as an ASIC architect engaged on energy administration and DSP design, earlier than a spell at NVIDIA as a senior architect, after which again to AMD for a few years working with Jim on the {hardware} that powers AMD’s steadiness sheet at present. He left AMD to start out Tenstorrent with two different co-founders in 2016, has raised $240m in three rounds of funding, and created three generations of processors, the newest of which is delivery this 12 months. At least two extra generations are on the way in which.
Jim Keller has typically been described as a {hardware} ninja, or a semiconductor rockstar. His profession is filled with profitable silicon designs, such because the DEC Alpha processors, AMD K7/K8, HyperTransport, Apple’s A4/A5 processors, AMD Zen household, Tesla’s Fully Self-Driving chip, and one thing essential at Intel (in all probability). He now sits as CTO for Tenstorrent, engaged on the corporate’s next-generation processors for 2023 and past.
Tenstorrent is a pure-play fab-less AI chip design and software program firm, which implies that they create and design silicon for machine studying, then use a foundry to make the {hardware}, then work with companions to create options (as in, chips + system + software program + optimizations for that buyer). For people who know this area, this makes the corporate sound like every of the opposite 50 corporations out out there that appear to be doing the identical factor. The typical cut up with pure-play fabless AI chip design corporations is whether or not they’re centered on coaching or inference: Tenstorrent does each, and is already within the strategy of finalizing its third-generation processor.
IC: Who or what’s Tenstorrent, in your individual phrases?
LB: Tenstorrent is a start-up firm engaged on new laptop architectures which are aiming to primarily be the proper substrate for executing machine studying workloads. More data-heavy workloads have been rising and taking on, particularly the datacenter computing scene, however we wish…
